I know that it has Process Green and Process Blue but to what degrees I do not know.
Illinois Pinball had squares of the colors printed at where the bottom card tray is.
But the white color to the game was an off-white cream color. It was never Pure White
like what Classic Playfield Reproduction has done.

O.K. I pulled an N.O.S. playfield from Bally's second run of Eight Ball Deluxe.
The first coat of this color is very thin on this playfield you can see the wood grain
underneath the inks.
Best color match for this playfield was Pantone 1205C
Pantone Yellow 5.7 -------------- 3 5/8 pts.
Pantone Warm Red 0.6 ------------- 3/8 pts.
Pantone Transition White 93.7 ------- 60 pts.

I hope this helps.

I looked at my OEM Eightball Deluxe playfield that is older but has truer colors, that the
last EBD playfield does not have.
Note: adjust base cream color Pantone #1205 to....
Pantone Yellow 5.5 -------------- 3 5/8 pts.
Pantone Warm Red 0.4 ------------- 3/8 pts.
Pantone Transition White 94.1 ------- 60 pts.
The base cream color one this playfield is lighter than the one on the previous playfield
but in no way is it white as in Centaur or in any Bally game in this time period.
One needs to get a scale and measure out the inks and pigments and pretest
on clean veneer.

The sad truth is, that Bally used different vendors to do their silkscreening for them.
Also, the company got lazy on the quality of their products in the mid-1985's.
The overcolor saturation on the "newer playfields" is awful as to compare it against the former.
Also, a lot of fine details is completely lost; it is amazing to see all of the guns filigrees that
the older playfield has as compared against the newer. The colors shift to darker hues over
the runs of these playfields is sad.
I do not know if Classic Playfield Reproduction was able to capture all of the fine details that are
in the original Bally's Eightball deluxe. I know they did not capture the right hues.
